Application and February 20, 1905.. semi No. 246,430.

To all whom it may concern:

Be it known that I, ADOLPHUS S. DENNIS, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Adding and Recordin Ma'- chines; and I do declare that the following is a full, clear, and exact description of the ining machines, and-is an improvement in like machines patented b me, and more particularly in the machine escribed in Letters Patent of the United States dated April 26, 1904,

i No. 758,052 and the improvement consists in the arrangement and combination of parts substantially as herein shown and described, and more particularly pointed out in the claims.

Heretofore the operation of the machines invented by me were dependent upon the power of the operator alone and the various I parts were set and manipulated by,

actuatinlg hand. i n the present construction my object is toprovide power-driven mechanism to positively actuate the parts through the intervention of releasing-key levers which are merely adapted to select and set the powerdriven parts in motion and which in themselves requireno undue'pressure, but only a slight touch to depress the same.

- My aim as set forth in simple detail is, first, to move the paper-carrier. mechanically a predetermined distance by the depression of any one of a series of designating key-levers, and, second, to set in motion the mechanically-driven actuating parts for the adding and recording mechanism by depressing any one of a series of key-levers representing the digits and .the like. I

In the accompanying drawings, Figure 1 is a plan view of my improved machine, and Fig. 2 is a similar view enlarged and in section on line x as, Fig. 5. Fig. 3 is also a sectional plan view on line y y, Fig. 5, and on a still lower plane than Fig. 2. Fig. 4 is a side elevation of .the machine, and Fig. 5 is a vertical section front to rear on line u u, Fig. 9. Fig.6 isan enlarged sectional detail of one of the key-lever friction-clutches as at rest. is a central vertical sectional view of the n'iach'ine on line 1) 1, Fig. 9; and Fig. 8 is a similar vertical section taken on line If t, Fig. 9, but looking in the opposite direction and A from the opposite side of the machine.

9 is a vertical cross-section on line 22, Fig. 5, looking towardthe rear; and Fi 10 is a detail view showing the releasingnger for the locking-bar of the numeral-key levers. Fig. 1 1 is a rear elevation of the machine.

All of the views above described show the machine in a position of normal rest or prior to setting it for adding and recording any specified item. The first step in printing an item is to move and set the paper carrier or carriage (represented by A). to a predetermined position corresponding to the number of figures in the item, and this is accomplished in my present construction by depressin proper one of a series of keys B, arranged in a row or tier at the top and front of the ma chine. Each key B when actuated throwsin a friction-clutch C, mounted on shaft D, which is under constant rotation from power derived from main shaft D through pinion d on shaft D, a gear-wheel cl on shaft and in- 'termediate pinion (1 mounted on a short shaft d on standard d, Fig. 4. Each clutch C is adapted tov make one complete revolution and then stop and occupy the same relation and position as before, and a cam of a series of camsE of different camming action, is attached to each clutch member C and serves to not only move carriage Aby means of a suitable train of mechanism, but also acts to throw out a sliding stop F in the path o ffingers a on carriage A, Figs. 5 and 7, to limit its travel to correspond to the key depressed and the number of figures in the item to be recorded.

Carriage A is supported to travel on ballbearings running in races or grooves of bars a front and rear, forming part of saidcarriage, and in grooved bars g, forming art of an inner frame G of main frame H of the ma chine. At the rear end of carriage A and journaled in brackets or'extensions a) thereon is a set of rubber feed-rollers I 1, adapted to hold andfeed the paper strip X, upon which the items are to be printed. It will be understood in this connection that as carriage A is moved from starting position the paper strip X is fed upward .a definite dis tance to space the items to be printedbeneath previously-printed items and in columns, and this result is obtained by an initial pull upon upright arm a of rock-shaft a,

the

same, Figs. 2 and 5. The rock movement imparted to rock-shaft a is limited by arm a striking stop a and is preliminary to the movement of the carriage, all of which is brought about by a cord or cable J stretched over the top of the machine and attached at one end to a horizontally-arranged )ivoted cont-rolled arm 7', Fig. 9, and at the other end to the free end of an upright pivoted lever K, Figs. 2 and ,the cord or cable passing around a pulley j, mounted on frame H, Fig. 4, and having a button or engaging member 3' Fig. 9, adapted to bear against arm of. Lever K is connected near its lower end by link is to a rock-arm k, Fig. 4, fastened upon the end of cross-shaft k which carries a series of upright arms is, one for each cam E, Figs. 5 and 7, and ada ted to be engaged thereby to rock shaft whenever one of the several friction-clutches C is thrown into action. All of the clutch members C are alike, and a description of one will suffice for all. Thus, referring to Figs. 6 and 9, it is seen that each clutch member comprises a ring or disk 0, mounted to revolve within a fixed casin c and having a split ring 0 centrally wit in and surrounding shaft D. One end of ring 0 is engaged by set-screw c and the other end by a pin or plunger 0 which bears at its outer end against a spring-pressed pawl or do 0 pivotally mounted within slot 0 of lislr c. The rim or flange of easing c is notched or recessed at c to permit the free end of dog 0 to press outward and to rest therein and engage shoulder a and keep disk 0 from revolving and to limit it to one revolution for each actuation of its operating key lever B. Each lever B-is rovided with a spring controlled finger b, Fig. 5, adapted to bear against the free end of dog 0 and when said key-lever is depressed dog 0 is forced inward and plunger 0 clamps split ring 0 upon shaft D and causes disk C to make one complete revolution. Cam E, attached to one side of disk 0, revolves with it and throws arm k back, and thereby moves carriage A through the intermediate mechanism, as hereinbefore described. To stop carriage A at predetermined places corresponding to the selected key-levers B, each cam E is adapted to bear against a spring-compressed sliding stop F, mounted opposite thereto within a cross-bar Fig. 5, and which stop when engaged is t rown out in the path of projections or fingers 11, arranged in staggered relation on carriage A, so that each stop has its own engaging finger a and all are differently related to limit the travel of the carriage to varying distances.

Having taken the first step by depressing one of the key-levers B, and thereby causing carriage A to take its selected place, the second step in the operation of the machine consists in selecting and depressing one of the ten key'levers B which represent the digits a notched extremity I)".

and naught and which are located immediately below and in advance of levers B. Levers B are pivotally supported upon a crossrod 1; and have a right-angled portion provided with a trigger or finger b, Fig. 5, and

A pivoted crossplate I), suitably spring-controlled, engages each extremity b" and locks each lever against movement when carriage A is in its initial starting position, but releases the same when the carriage is operated, as will appear later. Each lever B has a friction-clutch member L, corresponding in every detail to clutches C, and like letters of reference are used for the detail construction of both series of clutches, Fig. 9. Clutch members L are also provided with cams L, which bear against corresponding pivoted levers L and serve to depress their free ends when a corresponding lever B is depressed and its clutch L thrown into action for one complete rotation, as is the case with clutches C, Fig. 7. This action results in printing the numeral selected uponpaper strip X, carried by carriage A, and also results in adding the amount represented to previously-recorded items on totalizingprintingwheels N. A further effect is to release carriage A to return to starting position by a step-by-step movement as each item is set down. The mechanism for obtaining these results comprise actuating rack-levers L having projecting arms or fingers Z, Fig. 7, at the rear of their pivot and with rack-teeth l at their ends which engage teeth on segments 0 of a cross-shaft 0, having bearings in frame G, Fig. 3. Shaft O is rocked or rotated varying degrees, dependent upon the lever actuated and which is provided for by having arms or fingers Z of the different levers L of different lengths and each toothed segment 0 of such length as to beengaged thereby, Fig. 9. Each lever L is independentlyo erated, and the teeth of arms orfingers Z an segments 0 are normally out of mesh to permit the rotation of shaft 0 by any one of levers L At one end of shaft 0 is a small bevel gear or segment 0, Fig. 3, meshing with a like gear or segment 0 on vertical shaft 0 having bearings in frame H. At the upper end of shaft 0 is an arm 0, Fig. 7, projecting to the' rear of the machine, and with a connectinglink 0 at its end which is attached to sliding type-bar R, mounted in slot r of cross-plate r, Fig. 11. Bar R is provided upon its rear face with a line of type representing the digits and naught and 1s normall at rest with naught opposite hammer S, ig. 11. When a lever B is depressed, the corresponding number represented by said lever is brought opposite hammer S, .the varying degree of sliding movement imparted to type-bar B being obtained by the varying degree of rock movement imparted to shafts O and O by rack-levers L A spring 0', Fig. 2, attached to an arm on shaft 0 and frame H, returns IIO -the parts to the same starting position after "each actuation. Hammer S is also actuated in proper time for printing the numeral brought forward on type-bar R, and this occurs through the me iumof a pivoted yoke ing from yoke L, isadapted to engage a spring-'- p sliding rod L, supported above the base-plate of the machine upon cross-pieces L. Rod Ll has an L- shaped head L at its rear, with a lip or extension which is adapte to strike pin S, depending from cross-shaft S, supported to rock in bearings at the rear of frame H. A rearwar'dlyextending arm S of shaft S is connected by link S with crank-arm S on cross-shaft S at successive columns of figures on the printingsl'p in line with the separate figures of the i m to be printed. Thus as head L moves the rear it engages a set-screw in the end of arm T on a vertically-pivoted post T and rotates the same on its pivot. Said post carries a set of fin ers on its opposite side, one ed and the other finger T pivoted atT and having a spring T attached to pull said latter finger down when disengagement is effected from ratchet-wheel T on spring control, which is em odiedin a spiral spring T, inclosed within casing T attached tostandard T" at the front of the machine.

[ Carriage A is attached at A to a flexible steel 50 tape A which stretches from side to side of the machine and passes around suitable drums A and A, respectively, drum A being mounted on shaft '1 and having tape A fastenedthereto.- This completes the train of partswhich control the movement of carriage A.

Now referring more particularly to the adding mechanism, whereby the total of any series of printed items is obtained and recorded, I further utilize rock-shaft O by mounting a segmental gear 0 thereon to actuate a segmental pinion o, sleeved to rotate onthe hub of ratchet-wheel '0 which is fastened upon 'a cross-shaft P, supported inbearings of frame G. A pawl 0 on pinion 0 engages by the totalizing-gears ratchet-wheel 0 and rotates the same and also shaft P, as much as is imparted through gear 0 and rock-shafts O. A like rotation is thereby imparted to a selector-gear P. free to slide but splined upon shaft P, and ear P transmits its rotation to any one of t e several ears Q in the bank of ears for the addin mec anism proper and w 'ch are complete in mesh with gears Q. This adding mechanism is full described and shown in my former Letters atent, and

hence a\ detailed descri tion thereof is not entered into herein. Su ce to say, that aseach lever B is actuated the numeral represented thereby is added to the totalizingears CK and as operated by gear P and gear Eac movement of carriage A-is followed by a like movement of selector-gear P, excepting that it is in a reverse direction and as produced by a second metallic tape P, attached to drum A and ,which also passes around drum A and back. Amovable bar P, supported to travel on ball-bearings'within a guiding-frame por-' tion G of frame G, has an arm attached to tape P at P and said bar carries a vertical plate with a right-an led arm P, slotted at 1ts end and en age with an annular groove in the hub 7 of gear P. Thus as carriage A moves selector-gear P also moves, but in the opposite direction, and en ages first one and then another of the gears according to the column represented by the items being printed. Upon the initial movement of carriage A a series of connected members are throwninto action to release the locking-bar b for key-levers B so that they may be actuated. This mechanism comprises a vertically-arranged trip-lever V, pivoted at its lower end to an ear on the base of connects with lever V above its pivot and is attached to a second pivoted lever V, which has a hook or catch at its upper free end, which engages and holds yoke L a short distance apart from rack-levers L until carv I I 5 trip or fin er V, pivoted at its center upon riage A moves. :As seen in Fig. 10, a short standard has one end bearing against oke L and its other end projecting over lookar 1), so that as said yoke is released from catch-bar V and is raised by the tension of spring V attached to arm L, said finger V is actuated and lock-bar b depressed'torelease key-levers B. it is imperative that the operator shall first actuate levers B to set the carriage before levers B can be depressed to throw the adding and printing mechanism into action.

I employ the same mechanism for printing as in my former machines, .a total-striking hammer being used to print the total upon With this construction paper strips X through the medium of a suitable printing-ribbon X, stretched across the face of cross-plate r and adapted to be wound upon spools X Power is applied to main drive-shaft D through the medium of a pulley D fastened thereon at one end, and in operation said shaft is under constant rotation.

A brief summary of the various operations of my improved machine discloses that a mere touch of the operator upon any one of the series of related keys B will automatically set carriage A at an predetermined place in the line of travel of said carriage and correspending to the value of the key actuated, that upon a depression of any one of a second set of keys B, representing the digits and naught,

the value'of a key depressed is automaticallyprinted upon a slip of paper carried by said carriage and in column formation thereon, and said carriage is automatically returned a step from its set position, and at the same time the value of the key depressed is automatically recorded or added to a set of totalizing-wheels, from which the total of all items set down upon the paper strip may be printed. A slight depression of keys B and B is all that is necessary to throw in the clutch members C and L, respectively, and as the balance of the mechanism is power-driven all .other actnations are mechanical, and the degree of force imparted to the mechanism is always the same and equal, and the throw of the various parts also always the same and equal. With my improved machine I gain not only a high speed of operation, but also equalize the strain and shock upon all the mechanism, and thereby prolong the life'of the machine, as well as to produce a uniform character of work.
